So my car has been sitting for sometime. The battery died on it, and I had to replace. All was fine, but shortly after driving on it, I experienced some poor idling as well as sputtering and some hesitation. It seems like it isnt firing on all cylinders. When this first started happening, I would let it warm up and it seemed to run fine after wards. I still had my power with no problems. One thing I noticed is that the temp gauge seems too flutter (dunno if that would be a hint to anything or not). I have had a similar issue in the past, and it was the MAF and had it replaced. It was the same sort of scenario, where it sat for a while, battery died and was replaced, then the MAF took a dump.

So any suggestions as to how to test if it is the MAF, maybe I have some fouled plugs, or bad wires?

Some others on another board suggested that it may be my fuel filter. This is something that I have personally never replaced. I have 48k miles on the car. It may have been replaced by Chevy back when it used to visit their service center. I bought one and will be replacing it today.
Any ides are appreciated.
